Description

  Embodiments described herein relate generally to a medical image diagnostic apparatus.

  An uninterruptible power supply called UPS (Uninterruptible Power Supply) is known as a device that supplies power to electrical equipment and information processing devices. The UPS is a power supply device that incorporates a battery or a generator in its own device, and can supply power to an electric device or an information processing device for a certain period of time even when a power failure occurs. Since UPS can supply power for a certain period of time, work and processing in electrical equipment, information processing apparatuses, and the like are prevented from being interrupted immediately (see, for example, Patent Document 1).

  In the medical field, it is difficult to generate diagnostic images due to interruption of work in the middle of an examination due to a power failure or the processing of medical equipment, depending on the condition of the subject or patient. It is possible to come.

  FIG. 3 is a diagram showing an example of the workflow list 110 stored in the storage unit 11 according to the present embodiment.

  As illustrated in FIG. 3, the workflow list 110 includes columns of “patient”, “scan”, “image reconstruction”, “image processing”, “image transfer”, and “urgency”. In the “patient” column, six patients from patient A to patient F are described.

  Since “Patient A” has completed all processing contents, “Done” is registered. For “patient B”, the processing of “scan” and “image reconstruction” is completed, and “done” is registered. “Patient B” does not require “image processing”, and “image transfer” is registered to indicate that the remaining 100 images are being transferred to the other party X (for example, workstation 400). Note that the “urgency” for the examination of “patient B” is not urgent and nothing is registered.

  Since “patient C” has completed the “scan” and “image reconstruction” processing, “done” is registered in the same manner as “patient B”. In addition, “patient C” indicates that “3D” processing for creating three-dimensional data in “image processing” is unprocessed and “image transfer” is for partner Y (for example, image interpretation device 500). The fact that transfer of 500 image data has not been processed is registered. In addition, “2” having the second highest urgency (priority or importance) is registered in the “urgency” for the examination of “patient C”.

  “Patient D” has registered “completed” because the “scan” process has been completed. In addition, “patient D” is registered to the effect that “reconstruction type 3” (for example, processing when a parameter is set for an individual part) is being performed in “image reconstruction” and the remaining 100 images are registered. Yes. Further, “patient D” does not need to perform “image processing”, and “image transfer” indicates that 800 image data has not been transferred to the other party X (for example, workstation 400). It is registered. In addition, “3” having the third highest priority is registered as the “urgency level” for the examination of “patient D”.

  “Patient E” has not yet been processed as a “scan” protocol 1 (for example, a mass screening protocol). In the “image reconstruction” process, “reconstruction type 2” (for example, The fact that 5000 processes (filter processing) have not been processed is registered. In addition, “patient E” is an unprocessed clinical application B (for example, large intestine analysis) of “image processing”, and “image transfer” is also 1000 images of image data for the other party X (for example, workstation 400). Has been registered to indicate that the transfer is unprocessed. In addition, since the “urgency” for the examination of “patient E” is not urgent, nothing is registered.

  “Patient F” has not yet been processed as “scan” protocol 2 (for example, contrast protocol). In “image reconstruction” processing, 7000 images of “reconstruction type 2” for image data are processed. The fact that the process is unprocessed is registered. “Patient F” does not need to perform “image processing”, and “image transfer” indicates that transfer of 500 pieces of image data to the partner Y (for example, the image interpretation apparatus 500) has not been processed. It is registered. In addition, “1” having the highest urgency level is registered as the “urgency level” for the examination of “patient F”.

  In the workflow list 110, the appointment apparatus 600 accepts examination appointments, and the patients are arranged in order from the top to the bottom. The modality 100 performs processing in the order of “scan”, “image reconstruction”, “image processing”, and “image transfer” for each patient. In addition, “scanning” and “image processing” require user intervention (operation by an operator such as an examination engineer or an interpretation doctor). On the other hand, “image reconstruction” and “image transfer” do not require user intervention and can be processed automatically. In addition, it is assumed that, among the above four processing contents, each processing can be processed in parallel with each other if any processing does not overlap with other patient processing. In this embodiment, “scan”, “image reconstruction”, “image processing”, and “image transfer” are set as units of processing.

  As shown in FIG. 5, the reconstruction processing time table 121 includes columns of “reconstruction type” and “required time (minutes / 1000 sheets)”. The column “Reconstruction type 1” indicates that it takes 3 minutes to process the reconstruction process (for example, processing when the pitch interval is thin) for 1000 sheets. The column “” indicates that it takes 10 minutes to process the reconstruction process (for example, the filter process) for 1000 sheets, and the column “Reconstruction type 3” indicates that the reconstruction process ( For example, it shows that it takes 5 minutes to process 1000 sheets of processing when parameters are set for individual parts.

  FIG. 6 is a diagram showing an image processing time table 122 for calculating the processing time of image processing, which is one of the processing management tables 111 according to this embodiment.

  As shown in FIG. 6, the image processing time table 122 has columns of “image processing type” and “required time (minutes / 1000 sheets)”. The “3D (three dimensions)” column of image processing indicates that the processing (for example, conversion to 3D image processing of large intestine analysis) requires 10 minutes, and the “clinical application A” column of image processing This indicates that the process (for example, blood vessel extraction function) requires 20 minutes, and the column “clinical application B” indicates that the process (for example, cardiac function analysis) requires 30 minutes.

  FIG. 7 is a view showing an image transfer processing time table 123 for calculating a processing time when image data is transferred to a transfer destination as image data, which is one of the process management tables 111 according to the present embodiment.

  As shown in FIG. 7, the image transfer processing time table 123 includes columns of “destination” as a transfer destination and “required time (minutes / 100 sheets)”. The “Destination X” column, which is the transfer destination, indicates that it takes one minute to transfer 100 sheets to that partner (for example, the workstation 400), and the “Destination Y” column indicates that partner. It shows that it takes 5 minutes to transfer 100 sheets to the image interpretation device 500 (for example, the image interpretation device 500), and the column “partner Z” transfers 100 sheets to the other party (for example, the image server 200). It shows that it takes 3 minutes to do.

(Emergency power supply inspection stop processing)
Next, the operation of the emergency power supply inspection stop process in the medical image diagnostic system 900 according to the present embodiment will be described.

  FIG. 8 is a flowchart showing an emergency power supply inspection stop process for selecting the process of the modality 100 of the medical image diagnostic system 900 in an emergency based on the degree of urgency. In FIG. 8, reference numerals with numbers added to S indicate steps in the flowchart.

  First, in step S001, a doctor in charge reserves an examination of a subject (patient) using the reservation apparatus 600. Since a plurality of attending doctors may reserve examinations of patients each of which is in charge, or a single attending doctor may reserve examinations of a plurality of patients, the modality 100 reserves these examinations (this is referred to as examination reservation). ). The process related to the input of the examination reservation is referred to as an initial setting process.

  In step S003, the workflow management unit 12 of the modality 100 determines whether or not the UPS communication unit 10 has received a notification from the UPS 700 (FIG. 1) that power supply has been started. If the UPS communication unit 10 has not received a notification from the UPS 700 that power supply has been started (step S003: No), the workflow management unit 12 proceeds to step S005, while the UPS communication unit 10 performs the UPS 700. If a notification indicating that the supply of power has been started is received (step S003: Yes), the process proceeds to step S009.

  In step S005, the workflow management unit 12 reads the workflow list 110 (FIG. 3) stored in the storage unit 11, and sequentially examines from the patient A to the patient F according to the order of examination reservations registered in the workflow list 110. To implement.

  In step S007, the workflow management unit 12 determines whether or not all of the examinations registered in the workflow list 110 are finished every time the process constituting the examination contents is finished, and all the processes are finished. If not (step S007: No), the process returns to step S003. The workflow management unit 12 determines whether or not the UPS communication unit 10 has started supplying power from the UPS 700 (step S003). When all the processes are completed (step S007: Yes), the process ends. To do.

  On the other hand, when the UPS communication unit 10 receives a notification that power supply has been started from the UPS 700 (step S003: Yes), the workflow management unit 12 executes a battery monitoring process (step S009).

  In step S009, the workflow management unit 12 obtains the power supply available time from the UPS 700 via the UPS communication unit 10, and can complete the processing within the power supply available time in descending order of urgency. Execute the process.

(Initial setting process)
Next, an initial setting process of the workflow management unit 12 according to the present embodiment will be described.

  FIG. 9 is a flowchart illustrating an operation in which the workflow management unit 12 receives an examination reservation from the reservation device 600 and registers the examination reservation in the workflow list 110 of the storage unit 11. In FIG. 9, reference numerals with numbers added to S indicate steps in the flowchart.

  In step S101, the workflow management unit 12 accepts an input of an examination reservation for a subject (patient) from the reservation apparatus 600 (FIG. 1). Note that the workflow management unit 12 is not limited to a new reservation, and accepts changes in urgency, changes in examination contents, and the like.

  In step S <b> 103, the workflow management unit 12 registers the examination reservation received from the reservation apparatus 600 and the change of examination contents in the workflow list 110 of the storage unit 11.

(Battery monitoring process)
Next, a battery monitoring process performed by the workflow management unit 12 based on the workflow list 110 will be described.

  10 to 12 are flowcharts showing the operation of the battery monitoring process performed by the workflow management unit 12 according to the present embodiment based on the workflow list 110. FIG. 10 to 12, reference numerals with numerals added to S indicate steps of the flowchart.

  In step S <b> 201, the workflow management unit 12 loads the battery monitoring program from the ROM into the RAM and reads the workflow list 110 and the process management table 111 from the storage unit 11.

  In step S <b> 203, the workflow management unit 12 supplies the power of the emergency power source (battery power) from the UPS 700 (FIG. 1) by the modality 100 (FIG. 1) to the output device 16 that is a display device. Let them know that they have received it. Here, an example in which the workflow management unit 12 presents that the output device 16 is supplied with power from the battery is illustrated in the drawing.

  FIG. 13 is a display example illustrating an example when the workflow management unit 12 according to the present embodiment causes the output device 16 to indicate that the battery is being used. The output device 16 displays in the display area 161 that “battery is being used” that power is being supplied from the UPS 700. In the present embodiment, it is assumed that power is supplied from the UPS 700 during execution of the processing shown in the workflow list 110 (FIG. 3).

  In step S205, the workflow management unit 12 checks the process being executed in the workflow list 110 and determines whether there is a process that does not require user intervention in the process currently being executed. If there is a process that does not require user intervention, the process moves to a connector A. On the other hand, if there is no process that does not require user intervention, the process moves to a connector B.

  FIG. 11 is a flowchart showing a continuation of connector A of the battery monitoring process in the present embodiment.

  In step S207 shown in FIG. 11, since there is a process that does not require user intervention, the time required until the process being executed is completed is calculated with reference to the process management table 111. For example, in the workflow list 110 of FIG. 3, the image transfer of the patient B and the image reconstruction of the patient D are being executed.

  Accordingly, the workflow management unit 12 refers to the image transfer processing time table 123 of FIG. 7 for the patient B, and the remaining 100 pieces of image data to be transferred to the other party X. The required time is calculated to be 1 minute. For patient D, referring to the reconstruction processing time table 121 in FIG. 5, since the remaining reconstruction of the reconstruction type 3 is 100 sheets, the time required for all reconstruction is 30 seconds. And the required time is calculated. In this case, since the workflow management unit 12 can perform two processes of image transfer of the patient B and image reconstruction of the patient D in parallel, the time required for completing these processes is one minute. Judge that there is.

  In step S <b> 209, the workflow management unit 12 transmits an acquisition request for the power supply available time to the UPS 700 via the UPS communication unit 10, and acquires the power supply available time from the UPS 700. When the required time is calculated as in step S207, the workflow management unit 12 makes an inquiry about the power supply available time to the UPS 700 via the UPS communication unit 10 each time.

  In step S211, the workflow management unit 12 compares the time required until the process calculated in step S207 is completed with the power supply available time acquired in step S209.

  In step S213, the workflow management unit 12 receives power supply from the UPS 700, determines whether or not it can be performed until the process being executed is completed, and if so (step S213: Yes), If the process proceeds to S215 and the process cannot be performed (step S213: No), the process proceeds to the connector C.

  In step S <b> 215, the workflow management unit 12 causes the output device 16 to present that the process being executed is completed within the power supply time for receiving power supply from the UPS 700.

  FIG. 14 is a display example illustrating an example in which the workflow management unit 12 according to the present embodiment causes the output device 16 to indicate that the processing is to be completed until the image reconstruction of the patient D and the image transfer of the patient B. It is. In the case of the workflow list 110 in FIG. 3, the time required for the image transfer of the patient B is 1 minute and the time required for the image reconstruction of the patient D is 30 seconds. Therefore, the output device 16 is displayed in the display area 162. Then, it is presented that the processing is to be ended after the above processing is performed. In FIG. 14, a confirmation button “Yes” for prompting the user to confirm is provided in the display area 162.

  In step S217, the workflow management unit 12 inhibits other processes from being performed in the workflow list 110 so that processes other than the processes being performed are not performed.

  In step S219, it is determined in step S213 that execution is possible, and it is determined whether or not processing that does not require user intervention has been completed. Then, the workflow management unit 12 waits until the ongoing process is completed.

  In step S221, after the processing is completed in step S219, or as processing after connector B in FIG. 10, the workflow management unit 12 refers to the workflow list 110 and includes the examination contents of the patient with the highest degree of urgency. First, the process to be performed is extracted.

  In step S223, the workflow management unit 12 determines whether or not the process has been extracted in step S221. If there is a process to be performed, the workflow management unit 12 moves to the connector D, and if there is no process to be performed. Moves to connector E.

  FIG. 12 is a flowchart showing a continuation of connector D of the battery monitoring process in the present embodiment.

  In step S225 shown in FIG. 12, for the process extracted in step S221, the time required until the process ends is calculated with reference to the process management table 111. For example, the continuation of the progress status of the workflow list 110 shown in FIG. 3 will be described.

  FIG. 15 is a diagram showing a workflow list 112 that shows the continuation of the progress status of the workflow list 110. The workflow list 112 in FIG. 15 has the same fields as the workflow list 110. 3 is different from the workflow list 110 of FIG. 3 in that the processes of the image transfer of the patient B and the image reconstruction of the patient D which were being performed in the workflow list 110 of FIG. 3 are completed in the workflow list 112 of FIG. This is a point updated to “Done”.

  The workflow management unit 12 refers to the workflow list 112 in FIG. 15 until the process when the unprocessed process is executed for the patient F to which “1” indicating the highest degree of urgency is attached is completed. Is calculated with reference to the process management table 111. The workflow management unit 12 refers to a scan processing time table 120 (FIG. 4) which is one of the process management tables 111, and calculates the time required for scanning the patient F. The workflow management unit 12 is scheduled to perform a scan of protocol 2 (for example, a contrast protocol) for the patient F, and calculates the required time as 20 minutes.

  In step S227, the workflow management unit 12 acquires the power supply available time (usable time of the UPS 700) from the UPS 700 (FIG. 1) via the UPS communication unit 10. For example, it is assumed that the workflow management unit 12 acquires information from the UPS 700 that “the power supply time is 25 minutes”.

  In step S229, the workflow management unit 12 compares the time required for the scan calculated in step S227 with the power supply time acquired from the UPS 700 of 25 minutes.

  In step S231, the workflow management unit 12 determines that the scan of the protocol 2 can be performed on the patient F because the power supply available time is 25 minutes and the time required for the scan is 20 minutes.

  In step S233, the workflow management unit 12 determines whether or not the process for the patient F requires user intervention (step S233: Yes). The output device 16 is made to present so as to perform a process requiring intervention (step S235).

  FIG. 16 is a display example illustrating an example in which the workflow management unit 12 according to the present embodiment causes the output device 16 to present the patient F to be processed (scanned). The output device 16 presents “Please scan patient F” on the display area 163 to allow the laboratory technician or the like to confirm “Yes” or “No”.

  On the other hand, when the user's intervention is unnecessary (step S233: No), the workflow management unit 12 causes the output device 16 to present the process (step S237).

  In step S239, the workflow management unit 12 waits for execution of a process (for example, scan) that requires user intervention presented to the output device 16, and the process (for example, scan) is performed from the input device 15. When an input for performing the operation is accepted (step S239: Yes), the presented process (for example, scanning) that requires the user's intervention is performed (step S241).

  On the other hand, when the patient F (subject) is not in the waiting room or is not ready to receive a scan (processing), the workflow management unit 12 receives an instruction from the input device 15 that the examination cannot be performed, It is determined that the process F cannot be performed (step S239: No).

  In step S243, the workflow management unit 12 extracts processing to be performed next in descending order of urgency. For example, referring to FIG. 15, the workflow management unit 12 extracts the image reconstruction of the patient F, or extracts the image processing as the next process to be performed from the patient C having the second highest urgency ( Step S243). If the process cannot be performed for the patient F, the workflow management unit 12 automatically sets the process for the patient C with the next highest urgency as an extraction target.

  In step S245, it is determined whether there is a process that has not yet been processed. If there is a corresponding process (step S245: Yes), the process proceeds to step S225, and the same process is repeated. On the other hand, when there is no process to be performed (step S245: No), the process proceeds to step S247, it is determined that all the processes performed by the modality 100 are completed, and the shutdown process of the modality 100 is performed (step S247). The battery monitoring process ends.

  Hereinafter, the continuation of the workflow list 112 of FIG. 15 will be specifically described.

  For example, referring to FIG. 15, the workflow management unit 12 extracts the process to be performed next (for example, image processing) for the patient C because the patient F cannot prepare for the process (for example, scan) in step S243. (Step S243). The workflow management unit 12 refers to the image processing time table 122 (FIG. 6), which is one of the processing management tables 111, for the image processing of the patient C, and the time required for “3D” (image processing) is 10 minutes. The required time is calculated (step S225). Further, it is assumed that the workflow management unit 12 acquires information that the power supply possible time is 25 minutes from the UPS 700 (FIG. 1) via the UPS communication unit 10 (step S227).

  In this case, the workflow management unit 12 compares the required time of 10 minutes until the image processing (3D) process performed on the patient C is completed with the power supply available time of 25 minutes acquired from the UPS 700 ( In step S229, it is determined that image processing (3D) can be performed (step S231). Since the image processing is processing that requires user intervention (step S233: Yes), the workflow management unit 12 informs the output device 16 that the image processing (3D) to be performed on the patient C is performed. To present.

  FIG. 17 is a display example illustrating an example when the workflow management unit 12 according to the present embodiment causes the output device 16 to present the patient C so as to perform processing (image processing). The output device 16 presents “please perform image processing of the patient C” on the display area 164 so that the laboratory technician or the like can confirm “Yes” or “No”.

  The workflow management unit 12 waits for whether or not to execute the process presented to the output device 16 (step S239), and when receiving an input from the input device 15 to execute the process (step S239). (S239: Yes), the presented processing (image processing) is performed (step S241).

  Here, when an input indicating that processing is to be performed regarding the image processing of the patient C is received (step S239: Yes), the workflow management unit 12 performs the image processing for 10 minutes. For this reason, the remaining power supply available time provided from the UPS 700 is 15 minutes.

  FIG. 18 is a diagram showing the workflow list 113 indicating the continuation of the progress status of the workflow list 112 after the image processing as the process for the patient C is completed. The workflow list 113 in FIG. 18 has the same fields as the workflow list 110. The workflow list 112 in FIG. 15 is different from the workflow list 112 in FIG. 15 in that the image processing of the patient C that has not been performed is updated to “Done” in the workflow list 113 in FIG. Is a point.

  The workflow management unit 12 extracts an image transfer that is scheduled to be performed next to the image processing of the patient C as a process to be performed next (step S243), and an image transfer processing time that is one of the process management tables 111. With reference to the table 123 (FIG. 7), the time required for image transfer of the patient C is calculated (step S225). Specifically, since the workflow management unit 12 transfers to the partner Y (for example, the image interpretation apparatus 500), the required time for transferring 500 pieces of image data (FIG. 18) is 25 minutes. Is calculated (step S225).

  The workflow management unit 12 again acquires the remaining power supply available time from the UPS 700 via the UPS communication unit 10 (step S227), and acquires information that the power supply available time is 15 minutes.

  In this case, the workflow management unit 12 compares the required time of 25 minutes for the image transfer of the patient C with the 15 minutes of the power supply available time acquired from the UPS 700 (step S229), and transfers the image for the patient C. Is determined to be impossible (step S231: No).

  Since the workflow management unit 12 cannot transfer (process) the image of the patient C, the workflow management unit 12 extracts the process to be performed next from the patient with the next highest urgency (step S243). In this case, the workflow management unit 12 determines that the image transfer process, which is the process of the patient D with the third highest degree of urgency, should be performed next (step S245), and the image transfer processing time table 123 (FIG. 7). ) To calculate the required time (step S225). The workflow management unit 12 is to transfer the image data of the patient D to the partner X (for example, the workstation 400), and there are 800 image data to be transferred of the image of the patient D (FIG. 18). The time required to transfer to the workstation 400 is calculated as 8 minutes.

  The workflow management unit 12 again acquires the power supply available time from the UPS 700 via the UPS communication unit 10, and acquires information that the power supply available time is 15 minutes (step S227). The workflow management unit 12 determines that the image transfer of the patient D can be performed (step S231: Yes), and is a process that does not require user intervention (step S233: No), so the process (image transfer) is performed. The image is presented on the output device 16 (step S237) and the image data of the patient D is transferred (step S241).

  FIG. 19 is a display example illustrating an example when the workflow management unit 12 according to the present embodiment causes the output device 16 to present the patient D to be transferred. The output device 16 presents “I will transfer the image of the patient D” to the display area 165 to allow the laboratory technician or the like to confirm “Yes”.

  As described above, when the workflow management unit 12 of the modality 100 receives a notification from the UPS 700 that power supply for the emergency power supply has been started, the medical image diagnosis system 900 according to the present embodiment acquires the urgency level. On the basis of the workflow list 110 and the process management table 111, the time required for the process is calculated for each process in descending order of urgency. In addition, the workflow management unit 12 acquires the power supply possible time of the power provided from the UPS 700 via the UPS communication unit 10, and determines whether or not the processing can be performed for each unprocessed process. , Select an unprocessed process that can be performed.

  Accordingly, the modality 100 according to the present embodiment selects a process that can be completed within the power supply available time supplied from the UPS 700 in units of processing based on the urgency level registered in the workflow list 110. Therefore, processing that can be performed within the power supply available time supplied from the UPS 700 can be reliably terminated.
